Got SB13U #2
connected and set up earlier this afternoon.....
Much improved over just one sub!
Didn't do anything in much depth, just level calibrated and re-ran ARC on my Anthem pre-pro. I've got such a bad room with super-limited placement options, I just didn't know how the space would handle a second sub. Although it's not perfect, it has really made a difference in, what I at least PERCEIVE as a smoother overall response (maybe better integration is more correct?) - the entire system just seems to blend much better now - whereas before it was possible, depending on what was going on, to localize the 1st sub when it was all by itself.
Before, bass sounded better at the left and right seating positions of a 3-person couch. NOW it sounds best at the MLP, but still sounds good at the other two positions, more even, not quite as much ooommpphh as the center position on the couch. But it actually sounds THE BEST standing behind the couch. HA, go figure.
I had to park the subs on either side of the room, and they are not equidistant, so I just averaged the distances for the distance setting in the pre-pro. Don't know if I should attempt to mess around with phase settings, or anything else for that matter. It sounds good, I'm sure it could sound better. The only thing I can do though is mess with the more technical features of the subs - placement is a non-factor - they have to be where they are (and it is not optimal, I know that, but I've got no choice in current situation) so trying to improve things with better placement is off the table.
Got a nice-sized dip around 50HZ, which is bigger with the two together compared to just running one or the other, so they both suffer from this. Gotta be a placement thing!
Even so, quite pleased with the preliminary results. Anybody out there wondering if they should try a second sub, DO IT.
Any advice on possible ways to improve, gladly accepted!
